I'm curious, how many people are aware of these sounds. I have designed, etched, and built my own switching power supplies along with winding my own transformers. I am aware of the source of the noise. So, does anyone else hear these high frequency sounds regularly?

I can hear my phone charging.

I have like 2 USB chargers that are really loud.

  • Belkin travel surge protector
  • 5-port USB hub
  • wireless charger

Thankfully none else!

I did when I was younger but I don't hear it since I hit around 30

I hear some of them. There's a real cheap one my parents got with a security camera thats real loud to me, but they don't hear it.

[โ€“] [email protected] 2 points 9 months ago

Yes, but a bit less as I've aged probably because the higher frequency hearing we have starts to diminish the older we get.

[โ€“] [email protected] 2 points 9 months ago

Yes, but generally only bad quality loud ones.

I used to think I do, but I convinced myself I have a tinnitus.

Since I got older this got better. One benefit I guess?
